the ultimate in 'use what's laying around here'

wandered onto this site tonight, and just had to share it

enjoy..I definitely did :wee:

So you're the one who took the BIG box of Legos from my trash a while back.

[vladdy]

nah...it was some fellow in the netherlands??
I wandered a bit more just now on his site, and he has a different idea for a hobby cnc mill, looks like he wants to use a center pivot on the y axis, as opposed to a linear movement...and the z also..

even has some avi files on the site showing animation for that style..

I think I'd like to see it up in a real mill...bit of tricky prgramming math when you run y and z planes both on an arc

Interesting. I wonder if the kids would miss their Legos...

LMAO absolutely awesome Quality Stuff!

This is pretty darn neat. I wonder what kind of accuracy he gets?

You threw away a box of LEGO?! What's wrong with you!!

I'm going to get my son an erector set for Christmas - maybe he can make a router before I get mine finished!

Those are both fantastic! Yup, I can see what I will be doing with the grandkids soon!

Those are pretty cool.

JavaDog- My oldest son threw away a box of Legos that was about 24" by 30" by 18" deep. It was FULL to the top. Regular Legos and the fancier mechanical style ones. I hated to see them go but like my name says-- I've got 2muchstuff.

I'm to busy to read all the cnczone forums, I actually noticed this in my server logs...

I like the other two Lego cnc's. I must admit, I cheated a bit, I used stepper motors and brass M3 thread instead of Lego motors. My theoretical accuracy using 400 step/rev motors, half stepping and M3 thread is in the atomic range. In practice I get about 0.5mm repeatable accuracy when milling in foam. I replaced the car-windscreen-fluid-pump motor + M5 drill-bit with a dremel and a 3mm ball-end mill.

The software splits long line segments into short ones and then converts the start and end point of each segment from 3D into angels of the mill, then into length of each motor spindle then into a step number for each motor. It can mill perfectly strait over the full working area.

This was just the prototype. the stepping software all works, I can import CAD in the visualMill demo program and use a small DOS program to do the actual stepping on a Pentium 166Mhz using 3 printer ports. I'm still working on building the real thing in steel. (5 times bigger). Well, actually I'm doing 1000 other things at the moment. Maybe during the holidays (Know of any Dutch steel supplies that will ship during Christmas?)

I'm actually on the cnc-zone site as well:
